Beit known that I, TnEonoRE 0.NA1IVEL,

ofthe city and county of San Francisco, and

State of California, have invented a .new and Improved Portable Fire-Place 5 and I do hereby declare that the following is a full, clear, t

`of portable Jrire-place, designed to be used Y with an improved form of chimney-stack,

which requires no earth foundation, for which Letters Patent were granted me October 5, 1875. The portable fire-place is so constructed as to fit in the corner or any other portion of the room, and is constructed of lire-clay or other suitable material, with arrangements for ventilation and for preventing the burning of the wood-work, as 'hereinafter more fully described. Y

In the drawing, A represents the base-plate of the nre-place, which is made of a single piece of fire-clay, which may be bolted to any portion of the floor of the room, or fastened Said base-plate is provided upon its upper surface with two parallel channels or grooves, a a', which receive the lower edges of the two .casings B B'. These 'casings may be made of fire-clay or sheet metal, and either of a general angular shape, as shown, to adapt them to the corner of a room, or of any other shape to suit the place of their location. They are held below in the grooves a c' of the base-plate, and by anges or cornices b b upon the top plate O above, the said top'plate G and base-plate A being securely held together by tie-rods D. The air-chamber thus formed in the rear of the fire-place keeps the back or outer casing B cool, so that when the portable fire-place is placed near any kind of wood-work there will be no danger of charring or setting lire to the same. The inner top edge ofcase B is recessed or rabbeted at o, and upon the same, and fitting in the recess, rests a cap-piece, E. This cap-piece is straight upon its front edge,

andcorresponds upon,`its rear edge to the` shapeiof the casing B", which forms the back ofthe fireplace, a projection, d, upon the cap serving to hold thetwo casings B B the proper distance apart. This said cap-piece forms the top of the tire-chamber, and is perforated in the center for the escape of the smoke to the chimney-flue, and is also provided with a half-round depression, e, into which a corresponding connection for the chimney-tine its. F is this connection for the chimney Hue, which, though shown detachable, may be made in one and the same piece with the cap E. It consists of a halfround plate formed upon a section of pipe, f, which half-round plate fits in depression e, and which pipe connects with the central opening ot' the cap-piece below, and with the inner sections of the compound chimney stack above, the said stack being formed of an inner and outer pipe, with longitudinal intervening ribs and break-joints, as set forth in my previous patent. The tlueconnection F may be either a perpendicular half-round pipe, as shown in Figs. l and 2, or it may be a rectangular pipe and emerge obliquely, as shown in dotted lines, according to the location ofthe fire-place. y

To insure a draft in the air-chamber in the rear of the re-place, so as to ventilate the room and keep the back of the tire-place cool, registers Gr are placed in front, through which the air escapes from the room into t-he said air-chamber, and to give exit for the hot air the top part of cap E and the plate of thelueconnection F is fluted or channeled, so that the air may escape into the space between the inner and outer pipes of the ue. His the front plate, which has an open 'space 'for the fireplace proper, and above which the top plate projects, so as to form a mantel-piece.

When fuel is burned in the lire-place as thus described without a grate, some provision must be made to prevent the heating of the base-plate, and for this purpose the baseplate is provided with a raised edge, g, and upon the same is placed a false bottom, ll, made of tile, which is provided with an open space at i, and a projection, j. In front ot this open space is arranged a vertical tile-plate, J, which has at its bottoma recess that its upon projectionj, and a hollowed portion, h, that forms,

2 A ascel with the back B', a flue, which communicates with the space beneath the false bottom. Now, as this space is provided With air-holes at the front, a circulation of airis kept up under the false bottom and around the plate J, and the base-plate is alwaysy kept cool.

The fire-place as thus described is Well cemented at the joints, and the parts are rmly bound together by the tie-rods.

Having thus described my invention, wjhat I claim as new is- 1. The base-plate A, made'of earthenware,

and having channels a a', in combination with the two casings B B', the front plate H, the top plate C, the cap-piece E, and the tierods D, as and for the purpose described. 2. The-cap piece E, iluted or channeled upon its upper surface, and having a central smokepipe, in combination with the casings B B and the exterior flue-pipe, as and for the purpose described. l

3. The-cap piece E, uted or channeled uponv its upper surface, perforated centrally and provided with a depression, e, in combination with the exterior iiuepipe and the flue-connection F, consisting of a pipe, f, and a plate fitting in said depression, as and for the purpose described.

4. The combination, with the back B and lhe base-plate A, having a raised edge, g, of the false bottom I, having opening t', and the tile-plate J, located inside the fire-chamber, and having iue h, forming communication between the lire-chamber and the space beneath the false bottom, substantially as and for the purpose described.
